Specification of Letters Patent. Patented Apr. 29, 1913. Application filed November 1, 1912. Serial No. 729,112.

To all whom it may concern: Be it known that I, FREDERICK W. CARL- SON, avcitizen of the United States, residing at Helena, in the county of Lewis and Clark and State of Montana, have invented certain new and useful Improvements in Curtain-Rods, of which the following is a specification, reference being had therein to the accompanying drawing. I

This invention relates to curtain poles, and has for its object the production of a simple and efiicientpole which will support the curtain in such a manner as to prevent the curtain from sliding back and forth when it is not so desired.

Another object of' this invention is the production of a simple and efiicient curtain pole whereby the curtain supporting pins may be freely moved back and forth upon the pole under normal conditions, and the curtain' supporting portions will be held against accidental removal from the pole;

.In the drawings :Figure 1 is a small perspective view of the portionof the pole used in connection with the present invention. Fig. 2 is a bottom plan view of a portion of the ole showing the supporting bracket attac ed thereto. Fig. 3 1s a section taken on the line H of Fig. 2. Fig. 4 is a bottom plan viewpf one end of the pole. Fig. 5 is a transverse section through the pole showin the supportingbolts passa ing therethroug Fig. 6 is a sectional vlew' through the pole showing the modified form the present device.

By referring to the drawings by numerals, it will be seen that the pole 1 comprises an elongated body having a longitudinally extending slot 2 formed upon its lower. face, which slot extends througlibut the entire length of the pole 1. The side edges of the slot 2' are provided with notched portions 3 near one end thereof forfacilitating the lacing of the curtain su porting knobs 4 into the slot 2. The kno s 4 comprisean enlarged head 5 which is in the fern; of a ball and a depending lug .6 is formed upon the lower-edge of the ball 5 being square in cross-section. An a erture 7 is formed in the lug 6 through w ich is adapted to pass the curtain sup orting hooks 8. It will be seen that by aving the lugs 6 formed square in cross-section, the balls will be held against rotation within the pole 1 thereby at all times holding the curtain in its corof supporting pole used inconnection with rect position and" preventing the curtain with tubular portions 10 which tubular portions receive the ends of the pole 1, and these brackets are provided with laterally extending feet 11 for facilitating the attachmentof the bracket to a support.

. Suppprtmg bolts 12 pass transversely throng the pole 1 as illustrated in Fig.'-5, and these bolts 12 are provided with threaded ends 13 which threaded ends are adapted to be threaded intoa support 1 2 for support ng the pole I'in an operative position. A- ,bfnding nut' 15 isthreaded upon the bolt 12 and engages the pole 1 as indicated in F 5. The outer clamping nut 16 is threaded upon the outer end of the bolt 12,- and it will therefore'be seen that the pole 1 will be clamped betweentthe nuts' 15 and 16. The pole is, as illustrated in Fig. 5, thinnerat its lower edge than upon the top 17, and since the pole 1 is clamped between the nuts 15 and 16 it will be seen that by tightly threading the nut 16 upon the bolt 12, the edges 18 of the slot 2 may be firmly clam ed around the lug 6 so as to hold the ball against longitudinal movement with in t pole 1. A groove 19 is formed upon the outer end of the bolt" 12 for allowing W the bolt to be threaded into the support 14. As illustrated in Fig. 6, the bolt 12 may be provided with a squared shank portion 20 for allowing a wrench to grip the same for facilitating the threading of the bolt 12 into-e support. "It will be seen thatath'e nuts 21' and 22 will firmly clamp the pole 1 upon the bolt 12 and hold the same against longitudinal movement upon the pole.

From the fore oing it will be seen that a very eficient an endurable pole has been produced whereby the'curtain supporting books may be easily attached thereto. 1

said rod upon each side of said pole, and

said nuts being adapted to be adjusted prising a pole provided with a longitudinally extending slot, knobs working in said pole and provided with depending portion working in said slots, supporting bolts passing transversely through said pole and provided with a squared shank intermediate its ends for facilitating the threading of said rod into a Support, and clamping nuts positioned upon each side of said pole for firmly holding said pole in a set position upon said rods.
